UNITED STATES CLARENCE W. KEMPTON, OF LOS ANGIE-LES, CALIFORNIA GAS ENGINE Application filed August 8, 1927, Serial No. 211,514. Renewed March 18, 1981.

This invention relates to internalcombustion engines of the rotary type.

One of the objects of-this invention is to v assure a continuous functioning in the different steps during the rotating of a gas-engine including intake, compression, explosion and exhaust. I

Another object is to provide a rotor which may be acted upon on its periphery by which 1 the rotor can be caused to rotate.

Another object is to provide a compressor, cylinder and piston in radial relation to the rotor, including means by which compressed gas can be transferred to the periphery of the rotor where it may be caused to set the rotor in motion.

Another object is to provide a rotor with a spiral cam, whereby the gas-compressing mechanism may be operated.

Other objects will appear from the following description and appended claims as well as from the accompanying drawings, in which Fig. 1 is a fragmentary cross section through a cylinder enclosing a rotor and a compressing mechanism in radial relation to the rotor, the compressing piston being shown in the innermost position in"the rotor cam, in which position gas may be brought to explodeto act upon the cam of the rotor between the cam and the piston.

Fig. 2 is a similar view as Fig. 1, in whic the piston is shown in its compressing position within the compressing cylinder, the cam of the rotor being below the piston and the overfiow and communicating. channel connecting a space above the piston with a space below and sidewise of the piston, by which compressed gasis partly transferred from the space abo e to the space below and sidewise of the piston, poaratory to being discharged upon the cam of the 1 tor.

Fig. 3 is a similar illustration as Figs. 1 and 2 with the compressingrpiston ust forced into the cam of the rotor to the point of shutting off the overflow channel at which moment explosion may occur in the space below and sidewise of the piston to act upon'the cam of the rotor.

50 Fig. 4 is a fragmentary side elevation of a complete rotary motor, illustrating the feature of having several rotors within a single housing with a common manifold for the gas intake of the several rotors and another common manifold for the exhaust of the several rotors. v

Fig. 5 is a diagrammatic end elevation to illustrate the difierent positions of rotor cams in relation to one another in the manner of which the intake and outlet manifolds of a motor can be arranged straight across several rotors in a common housing in the manner illustrated in Fig. 4 and whereby a successive operation of several motors may be accomplished. Fig. 6 is a slightly modified form of a gas control forthe rotor including a valve controlled gas supply, whereby gas compressed by a separate'machinery,not shown in the drawings, can be injected into the housing to act upon the rotor instead of having indiclose enough to the point of explosion in relation to the rotor.

As illustrated in Fig. 1 of the drawings, the rotor 7 is mounted in a housing 8. 8 A compression cylinder 9 is arranged in radial relation to the rotor 7.

" A piston 10 is shiftable within the compres-' further illustration that means of various forms are known, in which cams can be made to positively move a cooperating member back and forth, so that in this case the compression piston 10 may be engaged with the cam in any well-known manner. No particular means is claimed or illustrated for this reason, but merely the spring 34 to make it known that the piston can be broughtdown.

Having thus described my invention, I claim:

1. In an internal combustion engine, a circular casing, a compression chamber extending radially from said casing and having a valve control-led gas inlet in its outer end, the walls of the compression chamber having a gas passage formed therein with its ends opening into the inner and outer end portions of the chamber, a rotor rotatably mounted in said casing and formed with a substantially radially extending face and having its edge face constituting a cam surface intersecting the ends of the radially extending face, a piston slidable in said compression chamber and extending into said casing and resting upon the edge face of said rotor, said piston having a recess in its lower end moved into and out of communication with the lower end of said gas passage during reciprocation of the piston and disposed opposite the radial face of the rotor when the piston is in a lowered position, and spark forming means to explode a charge of gas between the piston and radial face of the rotor.

2. In an internal combustion engine, a casing, a cylinder having a valve controlled fuel inlet and having its inner end open and communicating with said casing, a. rotor in 'said casing having a circumferentially extending cam surface and a shoulder joining ends of the cam surface, a piston slidable longitudinally in said cylinder into and out of said casing and at its inner end bearing against the cam surface of said rotor, the cylinder having a fuel passage opening into its outer and inner ends, said piston having movement across the inner end of the fuel passage and formed to define a. pocket to be filled with compressed fuel forced through the passage by the piston when the inner end of the fuel passage is uncovered as the piston moves outwardly, and means to explode fuel carried into the casing with the piston whereby the fuel will expand between the piston and shoulder of the rotor and impart rotary motion to the rotor.

3. In an internal combustion engine, a casing, a cylinder having a valve controlled fuel inlet and having its inner end open and communicating with said casing, a'rotor in said casing having a circumferentially extending cam surface and a shoulder joining ends of the cam surface, a piston slid-able longitudinally in said cylinder into and out of said casing, and at its inner end bearing against the cam surface of said rotor, the cylinder having a fuel passage opening into its outer and inner ends, said piston having movement across the inner end of the fuel passage and formed to define a pocket to be filled with compressed fuel forced through the passage by the piston when the inner end of the fuel passage is uncovered as the piston moves outwardly, and means to explode fuel carried into the casing with the piston, a

link extending transversely of the piston with one end pivoted to the piston and its other end pivoted to the casing, and resilient means acting upon said link to urge the piston toward the rotor.

4. In an internal combustion engine, a casing, a cylinder having a valve controlled fuel inlet and having its inner end open and communicating with said casing, a rotor in passage and formed to define a pocket to be CLARENCE w. KEMPTON.
